Abstract
The invention relates to a bending machine photoelectric protection safety device. A photoelectric switch (1) is installed below a knife edge of an upper mold (5) and rises and descends in synchronization with the upper mold. A group of control signals are connected to a control circuit for descending of the upper mold of a bending machine in series, the control signals are implemented by a relay KA, and the relay KA is controlled to start by the photoelectric switch. When a hand is protruded between the upper mold and a lower mold and in danger, the upper mold descends, the photoelectric switch is shield from light by the hand to generate a voltage signal, then the relay KA is started, the control circuit for descending of the upper mold is turned off, the upper mold stops descending, and the effect that the upper mold can not press on the hand is ensured. A travel switch (4) is connected between the photoelectric generated voltage signal and the control of the starting of the relay KA in series, and when the upper mold descends to a position, wherein a hand can not be protruded into a space between the upper mold in the position and the lower mold, the travel switch is switched off, even if photoelectric ultrared rays are shaded by the lower mold (6), the photoelectricity can not start the relay KA, and the upper mold keeps descending and bends metal plates.
Description
Technical field:
The present invention relates to a kind of bender photoelectric protection safety device.Protection is worked as hand and is put between upper and lower mould, and before hand was encountered in patrix decline, photoelectricity was by shading, and the photoelectric protection safety device is had an effect, and patrix stops descending, and protection operator hand is weighed wounded.
Background technology:
What occur now operates by the workman bender that carries out operation, in protection, the mold pressing hand is mainly by " carefully pressing hand " risk identification, emergency stop switch unclamps floor push, and upper die of bending machine speed slows down to control danger, when if the workman operates, technical ability is unskilled, tired operation, in operation in a flash, hand puts between upper and lower mould because of carelessness, is easy to cause industrial accident.
If with the grating protection, because the bending operation workpiece must carry out between grating, the grating protection can the normal bending operation of impact.
Summary of the invention:
The object of the invention is to overcome defects, and a kind of photoelectric protection safety device is provided, and solving present bender does not have a photoelectric protection difficult problem.
The solution of the present invention is: utilize glove finger thickness greater than common bending panel beating material thickness (0.5 to 3.5mm) difference used; Photoelectric safety device comprises photoswitc, relay, 24V direct-current switch power supply, travel switch.
Photoelectricity is arranged on patrix edge of a knife below, synchronize with patrix and rises and decline;
In the patrix stroke, travel switch is installed, effect is for, patrix descends, and when the spacing that can put in greater than hand between upper and lower mould, travel switch is connected, and photoelectricity is opened; Patrix descends, and when the spacing that can put in less than hand between upper and lower mould, travel switch disconnects, and photoelectricity is closed, bender bending sheet metal work.
Description of drawings:
Fig. 1 is the front views of apparatus of the present invention in bending, and Fig. 2 is the side view of device on bender, and Fig. 3 is circuit controling drawing.
The specific embodiment:
When patrix descends; during the spacing that can put in greater than hand between upper and lower mould; travel switch is connected, when hand puts between upper and lower mould, upper be molded into hand before; first shading; the voltage signal starting relay that photoelectricity produces cuts off patrix decline control circuit, and patrix stops descending; the protection hand is not weighed wounded, thus protection operator safety.
When patrix descends, when the spacing that can put in less than hand between upper and lower mould, travel switch disconnects, even photoelectricity is by the counterdie shading, the voltage signal that photoelectricity produces can starting relay yet, and the control circuit that patrix descends does not disconnect, patrix continues to descend, the bending sheet metal work.
Consider side during the workpiece of bending, the workpiece side can interdict light, can in apparatus of the present invention, install relay and buzzer between time-delay additional, the visible light laser locator.During bending, workpiece is placed on counterdie, side retreats into laser positioning point place, makes flanging can not interdict light, drops to the travel switch gap at cutting die, and time-delay relay stops 1 to 2 second with patrix, and send workpiece under the bending cutting die this moment again, bending workpieces.
The present invention is putting in when hand between the cutting die of up and down, and bender can be sensed fast by photoelectricity, makes patrix stop descending.Simple in structure, protection operator safe effect is good, and does not affect normal bending operation.
